An algorithm that runs in network bridges and switches to prevent loops, in which packets keep going around in circles. In a small network with one or two switches, the spanning tree protocol (STP) ...

Some people refer to Sun Labs distinguished engineer Radia Perlman as the Mother of the Internet and the creator of the spanning tree algorithm used by bridges and switches. Others know her as the ...

Jeff Hardee introduced me to the idea of using longer Spanning Tree Protocol (STP) path length values for high-speed links. I thought this was an intriguing idea and so I started to do some informal ...

Independent spanning trees, often realised as completely independent spanning trees (CISTs), form a foundational concept in network design and routing. They consist of multiple spanning trees ...

We consider a generalization of the classical minimum spanning tree problem called the generalized minimum spanning tree problem and denoted by GMST problem. It is known that the GMST problem belongs ...

Complex networks represent interconnected systems found in fields ranging from sociology to biology and technological infrastructures. A critical aspect of analysing such networks is the study of ...

We’re using IPTV at our school and have discovered a situation that we don’t understand. The video is delivered over a group of Ethernet switches. When we investigate the individual links, we find ...
